Servo - wider pulse range

Post by Jonit »

Hi,
i have just built my camera gimbal and found that i can't use my tilt servo as direct drive, because it causes lot of jitter in my camera. So i thought if it is possible to make wider servo pulse range from actual 1020 - 2000ms to 500 - 2500 ms, so servo will be able to move full 180 degrees without losing its resolution, so i can make a belt drive 1:2 reduction to smooth the movement.
But in code it says that you can't set it bellow 1020ms and above 2000ms

Code: Select all

#define SERVO_TILT
    #define TILT_PITCH_MIN    1020    //servo travel min, don't set it below 1020
    #define TILT_PITCH_MAX    2000    //servo travel max, max value=2000

So, I ask you, more experienced guys, if it is possible, or is this a hardware limit?
any help will be highly appreciated,
Thank you.
Jonit.
